BACKGROUND H. pylori infection significantly attenuated the expression of HSP70 in gastric mucosal cells. However, the role of HSP70 cancellation in H. pylori-associated cell damages is largely unclear. METHODS Small interfering RNA (siRNA) was used to down-regulate HSP70 in gastric epithelial cell lines AGS. The transfected cells were then incubated with(More)
The CKLF-like MARVEL transmembrane domain containing 3 (CMTM3) gene is a novel tumor suppressor with frequent epigenetic inactivation. In this study, we showed the role played by CMTM3 in gastric cancer cells as a tumor suppressor gene, and examined the correlation between CMTM3 expression and clinicopathological parameters using immunohistochemistry in(More)
UNLABELLED The paired box 5 (PAX5) is a member of PAX transcription factors family involved in the regulation of embryonic development. However, the role of PAX5 in carcinogenesis is largely unclear. We identified that PAX5 is involved in human cancer by methylation-sensitive representational difference analysis. We examined the biological functions and(More)
BACKGROUND/AIMS Mucosa marking targeting biopsy (MTB) technique has been tested and verified in animal model. For multi-focal atrophic gastritis, random biopsy may miss the point of atrophy, intestinal metaplasia or dysplasia. In order to monitor chronic atrophic gastritis on gastroscopy, get the proper biopsy sample is very important. METHODOLOGY(More)
Although JAK2 inhibitors can result in antitumor activity against various tumors, some tumors have showed insensitivity or resistance to the inhibitors. To investigate the possible mechanisms underlying responses of gastric cancer (GC) cells to AG490, a specific JAK2 inhibitor, human GC cell lines SGC7901 and AGS were used. AG490 did not significantly(More)
Native cellulose fibers were surface modified by poly(N,N-dimethyl aminoethyl methacrylate) (PDMAEMA) to generate an anion adsorbent, which was characterized by scanning electron microscopy, fourier transform infrared spectroscopy and elemental analyzer. This adsorbent had high efficiency in removal of F(-), AsO(2)(-) and AsO(4)(3-) from aqueous solutions,(More)
In this work, the degradation of atrazine by the combination of UV and chlorine (UV/chlorine) due to the formation of radicals during chlorine photolysis was systematically investigated in terms of efficiency, factors that influence the degradation kinetics, as well as oxidation products. It was found that the degradation efficiency of atrazine was enhanced(More)
INTRODUCTION Myocardial hypertrophy is an adaptive response of the heart to work overload. Pathological cardiac hypertrophy is usually associated with the ultimate development of cardiac dysfunction and heart failure. The mitochondria have an important function in the development of cardiac hypertrophy. However, mitochondrial adaptations to hypertrophic(More)
In creating a pattern classifier, feature selection is often used to prune irrelevant and noisy features to producing effective features. Manually developing a feature set can be a very time consuming and costly endeavor. In this paper, an efficient feature selection algorithm based on improved binary particle swarm optimization and support vector machine(More)
Stress-induced cardiomyocyte apoptosis plays an important role in the pathogenesis of a variety of cardiovascular diseases. Our early studies showed that HSP70 effectively inhibited apoptosis, but the underlying mechanism remained unclear. Fas-associated factor 1 (FAF1) is a member of the Fas death-inducing signaling complex (Fas-DISC) that acts upstream of(More)
